本考案は光フアイバー検出用ヘツドに係り、特に、光フアイバーの検出端部で 保持固定する光フアイバー検出用ヘツドに関する。 The present invention relates to a head for detecting an optical fiber, especially at the detecting end of the optical fiber. The present invention relates to a head for detecting and holding an optical fiber.
【０００２】[0002]
光フアイバーの検出端からの出射光を被検出体で反射あるいは透過させ、これ を光センサで受光するようにしたフアイバー式光電センサが広く使用されている 。 Light emitted from the detection end of the optical fiber is reflected or transmitted by the object to be detected, Fiber-type photoelectric sensors that receive light with an optical sensor are widely used. .
【０００３】 図１３ないし図１５は、それぞれ従来提案されている光フアイバーの検出用ヘ ツドの構成を示す説明図であり、図１６ないし図１８はこれら従来の光フアイバ ー検出用ヘツドを一般的に説明する説明図である。[0003] FIGS. 13 to 15 are views for detecting a conventionally proposed optical fiber, respectively. FIG. 16 is an explanatory view showing the structure of the stud, and FIGS. 16 to 18 show these conventional optical fibers. FIG. 3 is an explanatory diagram for generally explaining a head for head detection.
【０００４】 図１３は従来の光フアイバー式光電センサの光フアイバー検出用ヘツドの構成 を示す説明図であり、この図１３において１は筒体で、筒体１にはＮｉメツキを 施し黄銅製の軸芯を中心に２段状の挿通孔２が形成され、この挿通孔２には筒体 １の先端側に段部１ａが形成されている。また筒体１の外周には外径の異なる２ 種類のネジが切られていて、筒体１を取り付け部材にねじ込み固定する等してい る。[0004] FIG. 13 shows the structure of a conventional optical fiber type photoelectric sensor head for optical fiber detection. FIG. 13 is an explanatory view showing a cylindrical body 1 in FIG. 13 with a Ni plating on the cylindrical body 1. A two-step insertion hole 2 is formed around the center axis of the brass brass, and the insertion hole 2 has a cylindrical body. A step portion 1 a is formed on the front end side of 1. In addition, the outer circumference of the cylindrical body 1 has different outer diameters. There are various types of screws, and the cylinder 1 is screwed and fixed to the mounting member. It
【０００５】 この筒体１の挿通孔２には光フアイバー３が挿入され、挿通孔２の内面に接着 剤Ｐが塗布されて固着される。光フアイバー３の先端部分でポリエチレンの被覆 部３ａが除去されてフアイバー部３ｃが露出され、被覆部３ａの除去端面を挿通 孔２の段部２ａに当接させて、光フアイバー３は筒体１に固定されている。そし て、光フアイバー３のフアイバー部３ｃの一端、つまり検出端面３ｂが、接着剤 Ｐの硬化乾燥後に研磨され、検出端面３ａに塵埃などが付着しにくく汚れ難い状 態に処理されている。[0005] An optical fiber 3 is inserted into the insertion hole 2 of the cylindrical body 1 and adhered to the inner surface of the insertion hole 2. The agent P is applied and fixed. Polyethylene coating on the tip of the optical fiber 3 The portion 3a is removed, the fiber portion 3c is exposed, and the removed end surface of the covering portion 3a is inserted. The optical fiber 3 is fixed to the cylindrical body 1 by being brought into contact with the step portion 2 a of the hole 2. That And one end of the fiber portion 3c of the optical fiber 3, that is, the detection end surface 3b is adhesive. P is hardened and dried, and then polished so that dust or the like is unlikely to adhere to the detection end surface 3a and is hard to be contaminated. Is being processed.
【０００６】 また、微小物体を検出するために微小径の光スポツトを使用する場合には、光 フアイバー３からの出射光を絞る必要がある。この場合には、直径が０．５ｍｍ 程度の細径光フアイバーを使用するか、或いは図１５に示すように筒体１に光フ アイバーの端面部分を覆う遮蔽板１ｄが一体に形成され、この遮蔽板１ｄに所定 の微細径のピンホール５を設けてある。[0006] Also, when using a light spot with a small diameter to detect a small object, It is necessary to narrow down the light emitted from the fiber 3. In this case, the diameter is 0.5 mm Use a small-diameter optical fiber or use the optical fiber on the cylinder 1 as shown in FIG. A shield plate 1d is integrally formed to cover the end face portion of the eye bar. A pinhole 5 having a fine diameter is provided.
【０００７】 ところで一般には図１７に示すように、光フアイバー３のフアイバー部３ｃの 検出端面３ｂからは、軸芯に対してほぼ６０°の開き角で光が放出されるので、 この光を長距離位置まで伝送して検出を行なう場合には、図１４に示すように筒 体１の先端部に長距離検出用レンズアタツチメント７をねじ込んで使用する。こ のアタツチメント７は図１８に示すように、筒状に形成されていてその先端には 凸レンズ８がかしめ固定されている。[0007] By the way, generally, as shown in FIG. 17, the fiber portion 3c of the optical fiber 3 is Since light is emitted from the detection end surface 3b at an opening angle of about 60 ° with respect to the axis, When this light is transmitted to a long-distance position for detection, as shown in FIG. A long-distance detection lens attachment 7 is screwed into the tip of the body 1 for use. This As shown in FIG. 18, the attachment 7 is formed in a tubular shape, and its tip is The convex lens 8 is crimped and fixed.
【０００８】 このようにして、従来の保持構造によると、光フアイバー３を検出端部側で筒 体１に接着剤Ｐにより保持固定し、必要に応じてピンホール５ａを設けた筒体１ を使用し、或いは凸レンズ８が固定されたアタチメント７を取り付けることによ り、微小物体の検出や長距離位置の物体の検出を行なつていた。[0008] In this way, according to the conventional holding structure, the optical fiber 3 is attached to the tube at the detection end side. A cylindrical body 1 which is held and fixed to the body 1 by an adhesive agent P and provided with pinholes 5a as necessary. Or by attaching the attachment 7 to which the convex lens 8 is fixed. Therefore, it detects small objects and objects at long distances.
【０００９】[0009]
前述の従来技術では、筒体１の挿通孔２に挿通した光フアイバー３を接着剤Ｐ で筒体１に固定しているので、固定の作業が煩雑で接着剤Ｐの固化にも長時間を 要する。また、接着剤Ｐによる固定なので、光フアイバー３と筒体１の一方のみ が損傷した場合でも、光フアイバー３と筒体１の両方を交換することになり、維 持コストの面で不利であつた。 In the above-mentioned conventional technique, the optical fiber 3 inserted into the insertion hole 2 of the tubular body 1 is attached to the adhesive P. Since it is fixed to the cylindrical body 1 with, the fixing work is complicated and it takes a long time to solidify the adhesive P. It costs. Also, since it is fixed with the adhesive P, only one of the optical fiber 3 and the cylindrical body 1 is If the fiber is damaged, both the optical fiber 3 and the cylinder 1 will be replaced. It was disadvantageous in terms of cost of ownership.
【００１０】 また、接着剤Ｐによる固定のために、検出端部側で光フアイバー３の長さ調整 ができず、セツテイング時の長さ調整が不便であつた。即ち、従来の構造では図 １６に示すように、接着剤Ｐで固定されている検出端部側で光フアイバー３の長 さ調整はできないので、光フアイバー３の他端が接続されている本体６側で、チ ヤツク或いはねじ止めを解除し、光フアイバー３を所定長に切断し再度チヤツク 或いはねじ止めを行なう必要があつた。また、光フアイバー３のフアイバー部３ ｃの検出端面３ｂに対する研磨は、数種のサンドペーパとバフを使用し研磨処理 を繰り返す煩雑な工程が必要で、作業コスト上でも問題があつた。[0010] In addition, the length of the optical fiber 3 is adjusted on the detection end side for fixing with the adhesive P. It was not possible to adjust the length during setting and it was inconvenient. That is, the conventional structure As shown in 16, the length of the optical fiber 3 on the detection end side fixed by the adhesive P is Adjustment is not possible, check the main body 6 side to which the other end of the optical fiber 3 is connected. Release the screw or screwing, cut the optical fiber 3 to a specified length, and check it again. Or it was necessary to screw it. Also, the fiber portion 3 of the optical fiber 3 Polishing of the detection end surface 3b of c is performed by using several kinds of sandpaper and buff. It requires a complicated process of repeating the above procedure, which causes a problem in work cost.
【００１１】 また、微小物体を検出するために細径の光フアイバーを使用すると、光フアイ バーが損傷し易く、また、からまり易くなるためにその取り扱いが煩雑となる。 また、図１５に示すピンホール５を設けた構造では、先端部のピンホール５に塵 埃などが詰まつて光の出射特性が劣化することがあつた。[0011] Also, if you use a small-diameter optical fiber to detect small objects, the optical fiber Since the bar is easily damaged and easily entangled, its handling becomes complicated. Further, in the structure with the pinhole 5 shown in FIG. The emission characteristics of light may be deteriorated due to dust clogging.
【００１２】 また、図１４及び図１８に示す凸レンズ８が固定されたアタチメント７では、 アタチメント７のかしめ不良で凸レンズ８ががたついたり、かしめ力が強すぎて 凸レンズ８に傷を付け或いは割つてしまうこともあつた。[0012] In addition, in the attachment 7 to which the convex lens 8 shown in FIGS. 14 and 18 is fixed, The convex lens 8 rattles due to poor caulking of the attachment 7, or the caulking force is too strong. The convex lens 8 may be scratched or broken.
【００１３】 本考案は前記従来技術の課題に鑑み、これを解消すべくなされたもので、その 目的は、光フアイバーの検出端部に、接着剤を使用することなく、筒体を取外自 在とした光フアイバー検出用ヘツドを提供することにある。[0013] The present invention has been made in order to solve the above-mentioned problems of the conventional art. The purpose is to remove the cylinder from the detecting end of the optical fiber without using adhesive. It is to provide an existing optical fiber detection head.
